FIG. 2 is a schematic flowchart of a method for processing data according to the first embodiment of the present application. The processing method of the data includes:

Step 201: The user plane data processing network element parses the received data packet and determines first service type information of the data flow to which the data packet belongs.

In the embodiment of the application, the user plane data processing network element may be the UPF network element in FIG. The received data packet can be a user plane data packet. The user plane data processing network element may receive an uplink data packet from the terminal device, or may be a downlink data packet from the data network. In some embodiments, the service type information may be a specific service type, or may be the identification information of the service type (for example, the number of the service type), or may be the application identifier (application identifier) information, which is not limited herein.

In this embodiment, a packet flow is simply referred to as a data flow. The data stream can include at least one transmitted data packet. The data stream corresponds to packet flow description (PFD) information. PFD information is used to match the corresponding data stream. Specifically, the PFD information may include: triplet information, a uniform resoure locator (URL) significant part of the URL, and at least one of a domain name matching criteria (Domain name matching criteria) and PFD identification information. The triplet information includes: a server side IP address, a server side port number, and a protocol.

The user plane data processing network element determines the first service type information of the data flow to which the data packet belongs, and can adopt the following two methods:

In the first mode, the service data packet sent by the terminal device and/or the data network includes service type information. The user plane data processing network element can extract the service type information by parsing the data packet, so that the service type information of the data flow to which the data packet belongs can be determined. The service type information determined by the user plane data processing network element is referred to as the first service type information. In some implementations, service type information can be carried in the header of the data packet. The data packet may be one of a transmission control protocol (TCP) data packet, a user datagram protocol (UDP) data packet, and an internet protocol (IP) data packet.

In the process of establishing a service, for example, in a protocol data unit (PDU) session modification process, the policy control network element passes the service type information corresponding to the service through policy and charging control (policy). And the charging control (PCC) rule is sent to the session management network element, and the session management network element obtains the data flow corresponding to the service type information from the network exposure function (NEF) network element or the UDR network element according to the service type information. Description. After receiving the description information of the data flow, the session management network element associates the description information of the data flow with the service type information, and then sends the corresponding relationship between the description information of the data flow and the service type information to the user plane data processing network. yuan. After the user data processing network element receives the data packet, parsing the data packet may extract description information of the data flow to which the data packet belongs, for example, at least one of a server IP address, a server port number, and a transmission protocol. The user plane data processing network element can determine the service type information of the data stream to which the data packet belongs according to the correspondence between the description information of the data stream obtained by the parsing and the description information of the data stream obtained in advance and the service type information.

In the embodiment of the present application, the policy control network element may be the PCF network element in FIG. 1, and the session management network element may be the SMF network element in FIG.

In some possible implementation manners, after receiving the description information of the data flow and the service type information, the session management network element sends the description information and the service type information of the data flow to the user plane data processing network element. The user plane data processing network element associates the two to obtain a correspondence between the description information of the data stream and the service type information.

In other possible implementations, the data network may send the description information of the data flow to the policy control network element. The policy control network element sends the description information and the service type information of the data flow to the session management network element. The session management network element associates the description information of the data flow with the service type information, and then sends the description information to the user plane data processing network element; or the session management network element sends the description information and the service type information of the data flow to the user plane data processing. The network element is associated with the user by the user plane data processing network element. The data network may send the description information of the data flow to the policy control network element by using the AF network element.

In some possible implementation manners, the description information of the data flow may be all or part of the PFD information, for example, may be at least one of a server IP address, a server port number, and a transmission protocol.

Step 202: The user plane data processing network element obtains the second service type information of the data stream from the data analysis network element.

In an embodiment of the application, the data analysis network element may be the NWDAF network element in FIG.

In a possible implementation manner, the data analysis network element may perform big data analysis on the training data in advance to obtain a service recognition model. After receiving the data packet, the user plane data processing network element acquires the feature parameter corresponding to the data packet, and then sends the feature parameter to the data analysis network element. The data analysis network element inputs the feature parameter into the service recognition model to determine the service type information of the data flow to which the data packet belongs. The data analysis network element sends response information to the user plane data processing network element, where the response information includes service type information determined by the data analysis network element. The service type information determined by the data analysis network element is referred to as the second service type information.

For the method of determining the service type information according to the characteristic parameters, the data analysis network element can refer to the prior art; or, see the content of the Chinese patent application with the application number of 201710915784.4.

Step 203: The user plane data processing network element processes the data stream according to the first service type information and the second service type information.

When the user plane data processing network element determines that the first service type information and the second service type information are consistent, the user plane data processing network element sends the data stream to the terminal device or the data network. Specifically, if the user plane data processing network element receives the uplink data packet, the user plane data processing network element sends the data stream to which the data packet belongs to the data network. If the user plane data processing network element receives the downlink data packet, the user plane data processing network element sends the data stream to which the data packet belongs to the terminal device.

When the user plane data processing network element determines that the first service type information and the second service type information are inconsistent, the user plane data processing network element adjusts the processing priority of the data stream. The user plane data processing network element transmits the data stream to the terminal device or the data network according to the adjusted priority. In a possible implementation manner, the user plane data processing network element adjusts a processing priority of the data stream according to the second service type information. Specifically, the user plane data processing network element can reduce or increase the processing priority of the data stream.

In some possible implementations, when the user plane data processing network element determines that the first service type information and the second service type information are inconsistent, the method in this embodiment may further perform steps 204 to 207. The execution order of step 204 and step 206 in this embodiment is not limited.

Step 204: The user plane data processing network element sends the indication information to the access network device.

The indication information is used to instruct the access network device to adjust the priority of the data flow. After receiving the indication information, the access network device adjusts the processing priority of the data stream.

The user plane data processing NE sends the indication information to the access network device in the following two ways:

Manner 1: The indication information is sent by the user to the access network device.

The user plane data processing network element sends a data packet to the access network device, and the indication information is included in the packet header of the data packet. In a possible implementation, the content of the data packet is empty. The data packet can also carry description information of the data stream.

Manner 2: Sending indication information by controlling the access network device.

The user plane data processing network element sends a first message to the session management network element, where the first message is used to request the session management network element to adjust the priority of the data stream. After receiving the first message, the session management network element sends a second message to the access network device, where the second message includes the indication information. In some possible implementations, the second message may further include description information of the data stream. The indication information may be an adjusted priority of the data stream. The second message may include session management information including the indication information and/or description information of the data stream.

Step 205: The access network device adjusts the priority of the data flow according to the indication information.

Step 206: The user plane data processing network element acquires third service type information of the data stream sent by the terminal device or the data network.

Specifically, if the user plane data processing network element receives the uplink data packet, the user plane data processing network element sends request information to the data network, where the request information is used to request the data network to confirm the service type of the data stream. After receiving the request information, the data network sends response information of the request information to the user plane data processing network element, where the response information includes service type information confirmed by the data network for the data stream. The service type information confirmed by the data network for the data flow may be referred to as third service type information. The request information may also include description information of the data stream. The data network can confirm the service type of the data flow according to the description information of the data flow.

If the user plane data processing network element receives the downlink data packet, the user plane data processing network element sends the request information to the terminal device, where the request information is used to request the terminal device to confirm the service type of the data stream. After receiving the request information, the terminal device sends a response message to the user plane data processing network element, where the response information includes service type information that the terminal device confirms the data stream. The service type information confirmed by the terminal device for the data stream may be referred to as third service type information. The request information may also include description information of the data stream. The terminal device can confirm the service type of the data flow according to the description information of the data flow.

The user plane data processing network element can obtain the third service type information from the terminal device in the following two manners.

Manner 1: The request information is sent by the user to the terminal device.

The user plane data processing network element sends a data packet (for example, a first data packet) to the terminal device, and the packet header includes the request information. In a possible implementation, the content of the data packet is empty. The data packet can carry the description information of the data stream. After receiving the request information, the terminal device sends a data packet (for example, a second data packet) to the user plane data processing network element, where the data packet includes the third service type information.

The user plane data processing network element sends a third message to the session management network element, where the third message includes the request information. After receiving the third message, the session management network element sends a fourth message to the terminal device, where the fourth message includes the request information. Descriptive information of the data stream may also be included in the third message and/or the fourth message. In a possible implementation manner, the fourth message may include session management information, where the session management information includes the request information. After receiving the request information, the terminal device sends response information to the user plane data processing network element, where the response information includes the third service type information.

Step 207: The user plane data processing network element processes the data stream according to at least one of the first service type information and the second service type information and the third service type information.

When the first service type information and the third service type information are consistent, the user plane processing network element restores the priority of the data flow. The data stream is sent to the terminal device or the data network according to the restored priority. In this case, the user plane data processing network element may send the third service type information to the data analysis network element. The third service type information is used by the data analysis network element to update the service identification model. The user plane data processing network element may also send the description information of the data stream to the data analysis network element. The user plane data processing network element may also send indication information to the access network device, where the indication information is used to instruct the access network device to restore the priority of the data stream. For the manner in which the user plane data processing network element sends the indication information to the access network device, refer to step 204, and no further details are provided herein.

When the second service type information and the third service type information are consistent, the user plane processing network element maintains the adjusted priority of step 203 or adjusts the priority of the data flow again. The user plane processing network element can even abandon the transmission of the data stream. In some possible implementation manners, the user plane processing network element may also send report information to the operation support network element. The report information includes at least one of information of a traffic type abnormality of the data flow and cause information of a traffic type abnormality of the data flow. The operation support network element may be at least one of a network exposure function (NEF) network element, an element manager (EM), and an operations support system (OSS). The reason information of the service type abnormality of the data stream may be that the first service type information and the second service type information are inconsistent. The report information may also include description information of the data stream. After receiving the report information, the operation support NE sends an exception report to the policy control NE.

In some embodiments, the user plane data processing network element obtains the first service type information confirmed by itself and the second service type information from the data analysis network element. The service type of the data stream is confirmed by using two service type information, so that the service type of the obtained data stream is more accurate. The user plane data processing network element processes the data stream according to the first service type information and the second service type information, so as to avoid the problem of waste of network resources caused by the inaccuracy of the first service type information.

In another embodiment, when the first service type information and the second service type information are inconsistent, the user plane data processing network element acquires the third service type information from the terminal device or the data network, and uses the three service type information to use the data flow. The type of business is confirmed, which further improves the identification accuracy of the service type of the data stream.

In some embodiments, when the first service type information and the second service type information are inconsistent, the user plane data processing network element adjusts the processing priority of the data stream. Of course, the user plane data processing network element may not adjust the processing priority of the data stream first. After the user plane data processing network element obtains the third service type information, it determines whether to adjust the priority of the data stream according to the third service type information. . For example, when the first service type information and the second service type information are inconsistent, the user plane data processing network element may first cache the data stream to be transmitted. The user plane data processing network element determines the priority of the data stream according to the third service type information, and sends the buffered data stream.

In the above step 202, the user plane data processing network element obtains the second service type information of the data stream from the data analysis network element. In other embodiments, the user plane data processing network element itself may also implement some or all of the functions of the data analysis network element. For example, the data analysis network element can obtain the service identification model of the data stream by analyzing the big data of the training data. Then, the data analysis network element sends the service identification model to the user plane data processing network element. After receiving the data packet, the user plane data processing network element obtains the second service type information by using the service identification model. For another example, the data analysis network element can obtain the description information of the service identification model of the data stream by analyzing the big data of the training data. Then, the data analysis network element sends the description information of the service identification model to the user plane data processing network element. The user plane data processing network element generates a service identification model according to the description information of the service identification model. After receiving the data packet, the user plane data processing network element obtains the second service type information by using the service identification model. The description information includes at least one of feature set information, model parameter set information, and data type and data source correspondence corresponding to the service identification model.

FIG. 4 is a schematic flowchart of a method for processing data according to a third embodiment of the present application. This embodiment is based on the first embodiment, and the user plane data processing network element receives the uplink data (from the terminal device) for illustration. The processing method of the data in this embodiment includes:

Step 401: The user plane data processing network element acquires a correspondence between the description information of the data stream and the service type information of the data stream.

In some possible implementation manners, in the process of establishing a service, for example, in a PDU session modification process, the policy control network element sends the service type information corresponding to the service to the session management network element by using the PCC rule, and the session management network element is configured according to the The service type information is used to obtain the description information of the data flow corresponding to the service type information from the NEF network element or the UDR network element. In this embodiment, the description information of the data flow is used as the PFD information. After receiving the PFD information, the session management network element associates the PFD information with the service type information, and then sends the corresponding relationship between the PFD information and the service type information to the user plane data processing network element, so that the user plane data processing network element Obtain the correspondence between the description information of the data flow and the service type of the data flow.

In some possible implementation manners, after receiving the PFD information and the service type information, the session management network element sends the PFD information and the service type information to the user plane data processing network element. The user plane data processing network element associates the two to obtain a correspondence between the PFD information and the service type information.

In some possible implementations, the data network may send PFD information to the policy control network element. The policy control network element sends the PFD information and the service type information to the session management network element. The session management network element associates the PFD information with the service type information, and then sends the PFD information to the user plane data processing network element. Alternatively, the session management network element sends the PFD information and the service type information to the user plane data processing network element, where the user plane The data processing network element associates the two. Optionally, the data network may send the PFD information to the policy control network element by using the AF network element.

Step 401 is an optional step when the user plane data processing network element can extract the service type information from the service data packet sent by the terminal device and/or the data network.

Step 402: The user plane data processing network element receives the data packet from the terminal device.

The data packet can be an upstream user plane data packet. After receiving the data packet, the user plane data processing network element parses the data packet.

In some possible implementations, the user plane data processing network element parses the data packet, and extracts service type information of the data stream to which the data packet belongs, for example, a service type.

In some possible implementation manners, the user plane data processing network element parses the data packet, and extracts, from the data packet, description information of the data flow to which the data packet belongs, for example, a server IP address, a server port number, and a transport protocol. At least one of them.

In some possible implementations, the user plane data processing network element receives a feature list or a feature index list from the data analysis network element. The user plane data processing network element acquires a feature parameter corresponding to the feature list or the feature index list of the data packet.

Step 403: The user plane data processing network element determines the first service type information of the data stream.

In some possible implementations, if the user plane data processing network element extracts the service type information from the data packet, the service type information is determined as the service type information of the data flow to which the data packet belongs, that is, the first service. Type information.

In some possible implementation manners, if the user plane data processing network element does not extract the service type information from the data packet, the user plane data processing network element according to the description information of the data stream extracted from the data packet and step 401 The obtained correspondence relationship determines the service type information of the data flow, that is, the first service type information.

Step 404: The user plane data processing network element sends the feature parameter to the data analysis network element.

Specifically, the user plane data processing network element sends the feature parameter obtained in step 402 to the data analysis network element. The feature parameter is used by the data analysis network element to determine the service type of the data flow to which the data packet belongs.

In this embodiment, step 404 may be performed first, and then step 403 is performed. That is, in this embodiment, the order of execution of step 403 and step 404 is not limited.

The data analysis network element sends the determined service type information to the user plane data processing network element. The service type information may be a specific service type, or may be an indication of a service type, for example, a service type number, which is not limited herein.

Step 406: The user plane data processing network element determines whether the first service type information and the second service type information are consistent.

Specifically, if the first service type information and the second service type information are consistent, the user plane data processing network element sends the data stream to which the data packet belongs to the data network. The processing priority of the data stream can be unchanged. If the first service type information and the second service type information are inconsistent, the user plane data processing network element adjusts the processing priority of the data stream. The data stream is then sent to the data network based on the adjusted priority. In a possible implementation manner, the user plane data processing network element adjusts a processing priority of the data stream according to the second service type information. Specifically, the user plane data processing network element can reduce or increase the processing priority of the data stream. In the present embodiment, the priority is reduced by way of example. For example, the user plane data processing network element may reduce the processing priority of the data stream by one level according to a pre-configuration; or the user plane data processing network element may lower the priority of the data stream according to the priority information from the session management network element. .

When the first service type information and the second service type information are inconsistent, the user plane data network element may also perform the following steps:

Step 408: The user plane data processing network element sends the indication information to the access network device.

In an embodiment of the application, the indication information may be first indication information. The indication information is used to instruct the access network device to adjust the priority of the data flow.

Step 408c: The session management network element sends a second message to the access network device.

After receiving the first message, the session management network element determines the adjusted priority of the data flow according to the policy information. For example, the session management network element can obtain policy information from the policy control network element. The second message includes indication information. In some possible implementations, the second message may further include description information of the data stream. The indication information may be priority information after the data stream is adjusted. The second message may include session management information including the indication information and/or description information of the data stream. For example, the session management information may be N2 SM information.

Step 409: The access network device adjusts the priority of the data flow.

Specifically, after receiving the indication information in step 408, the access network device adjusts the processing priority of the data stream corresponding to the data packet according to the indication information.

The response information may also include description information of the data stream.

Step 412: The user plane data processing network element determines whether at least one of the first service type information and the second service type information is consistent with the third service type.

If the first service type information and the third service type information are consistent, steps 413 to 416 are performed. If the second service type information and the third service type information are consistent, step 417 is performed.

Step 413: The user plane data processing network element sends the third service type information to the data analysis network element.

The third service type information is used by the data analysis network element to update the service identification model.

Step 414: The user plane processes the priority of the network element to recover the data stream.

In a possible implementation manner, the user plane processes the priority of the data stream before the network element recovery step 407. The user plane processing network element sends the data stream to the data network according to the restored priority.

Step 415: The user plane data processing network element sends the indication information to the access network device.

In an embodiment of the application, the indication information may be second indication information. The indication information is used to indicate that the access network device restores the priority of the data flow. For the manner in which the user plane data processing network element sends the indication information to the access network device, refer to the description of step 408.

Step 416: The access network device adjusts the priority of the data stream.

Specifically, after receiving the indication information in step 415, the access network device recovers the processing priority of the data stream corresponding to the data packet according to the indication information.

The report information may also include description information of the data stream.

After receiving the report information, the operation support NE sends an exception report to the policy control NE.

In some possible implementation manners, if the second service type information and the third service type information are consistent, the user plane processing network element maintains the adjusted priority of step 407 or adjusts the priority of the data flow again. The user plane processing network element can even abandon the transmission of the data stream.

In some possible implementations, if the third service type information is inconsistent with the first service type and the second service type information, the user plane processing network element may perform the operations in step 417.

In this embodiment, if the first service type information and the second service type information are inconsistent, the user plane data processing network element adjusts the priority of the data flow (steps 407 to 409), and then performs a verification process (step 410 to step). 412). In other implementations, when the first service type information and the second service type information are inconsistent, the user plane data data processing network element may not adjust the priority of the data flow (ie, step 407 to step 409 are not performed). The verification process is performed, and the priority of the data stream is adjusted according to the verification result.

In an embodiment, in step 404 and step 405, the user plane data processing network element obtains the second service type information of the data stream from the data analysis network element. In other implementations, the user plane data processing network element may also obtain the description information of the service identification model or the service identification model from the data analysis network element in advance. After receiving the data packet, the user plane data processing network element obtains the second service type information by using the service identification model. In this way, the data processing flow can be simplified. For example, the interaction process between the user plane data processing network element and the data analysis network element can be reduced, and the system burden can be reduced.
